| 摘 要： | 针对突发频段超出瞬时接收带宽的突发信号宽带检测概率计算问题,建立信号宽带检测问题模型,结合信号特征检测算法参数,分析扫描及守候接收策略下未知参数突发信号的检测概率计算方法,推导两种接收策略下检测概率理论计算公式,采用计算机仿真验证推导结果的可靠性。理论分析表明在信号特征持续时间较长时采用扫描策略进行信号检测要优于采用守候策略,理论仿真结果可指导突发信号最优检测策略的选择。

| Abstract: | This paper focuses on the detection probability calculation question when the burst signal'appearing bandwidth is bigger than the instantaneous receiving bandwidth.The burst signal detection model is established.Detection probabilities with unknown parameters are analyzed under fixed and scanning receiving strategy.The theoretical probability formulas are deduced under the above two receiving strategies.The reliability of the formulas is testified by computer simulations.Based on the theoretical formulas,it... |
